As the stud is shifted laterally along the major axis of the two circular orifice the stud diameter is smaller than the adjoining intersection point of the two circular orifice w herein the adjoining intersection point locks the stud from laterally shifting along the major axis of the two circles the smaller circular orifice prevents the stud head from removal as described in FIG. 3 locking together the assembly of a participant's or competitor's number 8 and an athlete's apparel 7 in place without damage to the aforesaid apparel.
(30) Referring now to EP1634508 System for fastening the competition numbers or bibs on the garment of an athlete, and comparing and contrasting with aspects of the present invention, there is observed no allowance for differences in material thicknesses of an athlete's apparel provided in EP1634508 in the description or claims. Such allowance for material thickness, although small, is essential to provide a snap fit of the two attaching plates and to provide a definite physical or audible indication of connection to the wearer. If this were not the case as in EP1634508 there may be occasions when an athlete would assume a connection has been made only to be disappointed mid-way through a race, for example, when the identification number comes adrift. In all the embodiments of the present invention this allowance is provided for by the flexible plastic-lipped vanes first described in FIG. 3, which adjust by flexing to make allowance for varying thicknesses, folds or creases of typical apparel and participation numbers worn for sporting activities and thus facilitating a positive snap-fit connection, indicating to the athlete audibly, or in a tactile manner, or both that a secure connection has been made.
(31) Furthermore, the disc shaped body 5 as described in EP1634508 does not have a strengthening function, which is provided for by the elastic vanes 6 in the present invention. In addition due to the coaxial activity in the shank as described therein EP1634508, the annular head of the shank is made bigger and increases the forces acting upon the fastener by the material and the deformation of the competitor's apparel. It will also be understood that as a result there would be no film indication to the user that the two halves of the fastener had connected securely. In the description the washer with the central hole requires the annular head to lock all the way around the circumference otherwise it would work loose and come apart.
(32) By contrast with EP1634508 the present disclosure includes embodiments having one or more of the following features: 1. A single flexible vane or lip opposing a single solid edge or lip within the orifice in plate 1, a stud 3 and a stud head 4, as opposed to an annular projection or ring, in plate 2. 2. An integrated self-locking function which locks plate 1, as opposed to an automatic button operation principle. 3. Elasticated deformation lip. 4. A stud which passes through from the inside surf ace of the assembly. 5. Uses the thickness of the apparel to lock plate 1 to plate 2.
(33) The present invention also differs by using the thickness of the apparel to lock plate 1 to plate 2.
(34) For ergonomic reasons the dimensions of plate 1 are less than the dimensions of plate 2. Being a self-locking fastener the present invention has further uses other than attaching sporting identification event numbers without piercing or damaging a participant's or competitor's apparel. These include, dance competitions and game show events.
(35) Referring now to the following patents, by contrast with U.S. Pat. No. 2,981,992 A, FR864346 A, FR1350098 A, NL6611411 A, GB951000 A, WO92/04837 A1 fastening systems the present disclosure includes embodiments having one or more of the following features: 1. A single flexible vane or lip opposing a single solid edge or lip in plate 1. 2. A self-locking function which locks plate 2 to plate 1. 3. Elasticated deformation lips which friction-flex. 4. A plate 2 featuring an integral stud mounting which is fanned to engage and interlock diagonally with a plate 1. 5. A plate 1 featuring a single chamfer across the perimeter to act as a hinge for angled engagement and facilitates balanced angled release of the plate 1 against the plate 2. 6. Elliptical stud head.
(36) The present invention also differs by using the thickness of the apparel to lock plate 1 to plate 2 and can secure event numbers and other identification to apparel also a device or object.
(37) It will be appreciated by those skilled in the art that any number of combinations of the aforementioned features and/or those shown in the appended drawings provide clear advantages over the prior art and are therefore within the scope of the invention described herein.
(38) The foregoing description details certain preferred embodiments of the present invention and describes the best mode contemplated. It will be appreciated, however, that changes may be made in the details of construction and the configuration of components without departing from the spirit and scope of the disclosure. Therefore, the description provided herein is to be considered exemplary, rather than limiting, and the true scope of the invention is that defined by the following claims and the full range of equivalency to which each element thereof is entitled.
